I enjoy the concept of cranking up the power as far as it will go in any motor, but there isn't really anything exciting about a 4-cylinder to me even if it does make insane power...

Like Nissan has a 1.3L 3-cylinder engine that makes 400HP, neat but I wouldn't want it in any of my products... It would have the life expectancy of a mayfly.

Yep. Race car application, not mass production. Race car engine break down every race, if not during the race, and they tear it down and rebuild after the race, or they got spare engine waiting in the pits.

Oh, you mean what Ben Shapiro said? Thanks for pointing out the obvious.

The leftist mentality is to smash someone in the face for disagreeing with you, run them out into the streets for not belonging to the approved political party, mob against them wearing masks and hoods screaming that you can’t hold opposing opinions outside in public places, admit you lied about a man while giving testimony because you’re angry, accuse children of assaulting Native American elders (and after being proven wrong about that with video evidence, doubling down on the lie), shriek aloud that today you are GUILTY GUILTY GUILTY UNTIL PROVEN INNOCENT and as elected, public officials decree that “just because we can’t prove you’re innocent, you are to be investigated ad infinitum.

I thought that was the outrage mentality both sides used whenever it was convenient for them...

Yes, for those on the "bleeding edge". I would like to think that they will work the bugs out over time and it will be just another boring turbocharged four cylinder engine. Just look at the humble beginning of Group A boosted 2.0 liter fours. Cranked up and boosted to within an inch of their lives. That was back when 4 cylinders were considered powerful if they managed anything over 65 hp. LOL. Now we don't even bat an eye at the 2.0L turbo fours today that pump out the old Group A level power levels of over 200hp. In econoboxes no less. I would like to think that the ICO can continue to evolve and improve before the inevitable rise of the all-electric vehicles with the insane instant accelerations numbers we have seen from top end Tesla's. That said, I would not recommend the first year production run of this engine. However, something tells me that people that can afford this car don't care as they will have extra cars and assistants that can deal with the trips to the dealer's repair shop.

Wow. A lot of people had a bad day while reading this obviously satirical post. Please God do not have a political discussion on a Car forum. I mean, you will have people who bought an Alfa Romeo Giulia sharing their wisdom on critical political issues for Pete's sake...

Still better than shooting up abortion clinics, running over people with a Dodge Challenger, shooting up churches, and I left A LOT out.

The unreliability claim was said when AMG made the hyper 4 cylinder in the last gen, but not heard of any major catastrophic trends (unlike the Focus hopped up 4 cylinder). Hopefully AMG has is right again.

Tossing more cooling at an engine doesn't negate the fact a high boost low displacement/cylinder engine produces far more heat than a larger engine.

In fact it validates that point....

I see you have a vast grip on thermodynamics. Not.

Rejected heat is a function of horsepower produced minus the energy in the form of fuel shovelled into the engine, all on a prescribed time basis.

There is absolutely no other explanation.

So your statement that a high boost low displacement engine produces "more" heat than a larger engine is some myth you pulled out of your left ear. And THAT's a fact.

Jeez, sometimes I wonder why I studied to be an engineer when the walking around populace is so full of it, and know better than the educated people who actually design and make things. That's why we have politicians who after a coffee break and a "think" know more than the people who spend a lifetime on a subject.

Impressive indeed, but unreliability is the tradeoff. Forced induction small engines = high heat generators; high heat = inefficiency and inconsistency wrt performance.

Block construction, cooling methods and material selection play huge roles in determining engine longevity. Apparently you didn't read the article, which provides a quick summary of how MB has addressed that. I'm sure the full list if far more expensive and includes generously sized bearing of very high quality and so forth.

Great reply.

Just remember that engineering truism on sites such as this are oftentimes "wrong" by default because someone engineering has nothing whatsoever to do with automotive/engine design.

I think you miss-understood my point so let me clarify.

If two motors make identical power and have nearly identical designs one a NA 8-cylinder engine the other a turbo 4 both make 400HP both operating at peak power which of the two motors will run hotter.

The 4-cylinder engine has less surface area, needs to produce the same power with fewer cylinders, the exhaust system is instead redirecting hot gasses back into the engine bay instead of expelling them so it can spool up a turbo charger.

I honestly want to hear your opinion for how a smaller turbo 4 performs in such a scenario....

And come on we both know politicians are bought and paid for by big donors and lobbyists to purposely ignore recommendations provided by subject matter experts. They are corrupt through and through.

Yeah, who in their right mind would buy one of these cars used with a little 2.0 liter engine boosted like a teenager on 10 bottles of Red Bull?

People who can afford such a car and don't care so much about reliability. (and let's get this straight, it's not like Mercedes AMG cars break down like a dragster after a few runs)

Really man? Why are you even asking such a question. It's like asking why someone would buy a $3 million Chiron. They are paying for owning a piece of engineering marvel at that time in history. So I think paying for $80k for a Mercedes with this new 2 liter 416 hp engine has it's own honor for people who can afford paying such a price.

Thiae are some very impressive numbers especially without an electric supercharger which I assumed this would have. So naturally this begs the question, how much and where along the curve could an electric SC version make?

Given the torque peak being way up in the 5000 rpm range, I would have thought an electric supercharger would have made sense to reduce lag. MB may have done a pretty good job reducing lag overall, but this engine will surely have more than the base 2.0L turbo you can get in the base CLA.

This uses a twin scroll turbo, which itself reduces lag. And while it's presently speculative on my part, it may well be that MB has intentionally limited engine torque at lower RPMS in the interest of enhancing engine longevity.

Many I'm sure. There will be many patents on this too. Mercedes definitely has folks attention with this one. Heck, Ford's 2.7 EB can't hold a candle to this numbers-wise. What's the fuel mileage gonna be for this thing? No less that 91oct no doubt!

The Ford has more potential with 50% more cylinders and 35% more displacement, but as it stands Mercedes did an outstanding job with this engine.

You really can't compare the two...one is a hand-built exotic engine that just happens to have only four cylinders. The other is cranked out of a factory like candies flying out of a PEZ dispenser that also has to meet durability parameters for pickup truck duty.

Ford's 2.7, since it is FAR more mass produced, went a cheaper route, but still a good route in so far as block material for heat distribution and dissipation. High density aluminium in the AMG block sounds good on paper, and probably will be good in reality, is definitely reserved for low volume production. I still would trust graphite-ed iron, in the long run, with all that said.

Its insane! I love it. I assume the advantage is a more compact size and less weight compared to a turbo V6. Maybe better fuel economy. Hopefully is smooth and not with a lumpy idle. That would be out of place in a MB.

10 years ago the Evo X felt like it was squeezing "alot" of power out of 2.0L...and it was making 291 hp for the longest time. then more and more run of the mill German luxury sedans hit the streets with 240-250hp. this thing is insane. I wouldn't want to own one, but I think it's cool that it exists.

This is very cool and I'd love to try one out some day, however the current CLA engine gets 23/30 mpg and the 6.2l V8 I had in a 2014 Stingray was 17/28. In four years of driving I was getting 22 combined in the Stingray. Yes, this gets better mileage but 4 mpg?? Also, the GM V8 will easily run 20+ years with just gas and oil changes. When was the last time anyone saw a 20 year old Mercedes 4 cylinder engine still operating?? I like that it exists but I don't really see the benefit of it.

Yeap, after seeing the picture above of this mighty 2.0L atomic weapon, the question is "when will it break"? Better yet, MB can put 2 of these together by joining them as a V8 with 4.0L and 800+ HP.....begets the following question "twice as likely to break sooner?" Normally aspirated push-rod LS engines do last a long time, much longer than any over-engineered yet powerful MB (non-diesel) engine.

I believe I provide more sources and mathematical proofs than any other on the site.

If you have a problem with that, provide a specific example.

This article makes it clear than MB engineers have placed a heavy emphasis on material selection and cooling, each of which play huge roles in determining engine longevity. I'm sure the full list is far more extensive than the summary C&D has provided.

To date, there is ZERO PROOF that this engine's long term durability will be substandard to that of a GM LS based engine.

The final 7 liter production engine of Chevrolet produced 505 SAE net horsepower (2012 Corvette zo6). The beauty of such large engines is how they make such power without much effort compared to the low displacement high boost engine if Mercedes.

Imagine this being the 4 cyl option for the new Zupra. Oh wait, it's not BMW. Nonetheless still high performance, but with the familiar German unreliability. Deutch precision;) 60K mile lifepsan...then everything breaks down.

The CLA 45 will be one sweet car with this engine in it. Sounds like it's well engineered to hold together for the long haul. I would expect nothing less from a full, hand built in Affalterbach, AMG engine.

Super exotic race car technology for a compact sedan. I really like that Mercedes had the guts to make it, I see it as a Halo car to get the younger demographic in that grew up playing Gran Turismo. I also really like the detailed information on the engine, reassuring me that Mercedes really went out of their way to give the best of power and reliability. I would love to see the cylinder wall mirror finish and how they manage to get a good seal with forged pistons.

The reliability, actual gas mileage, etc will be interesting to read about over time, but DANG!! 416hp from a 2.0!! Crazy world when a 4 banger makes significantly more power than my 2017 daily with a V8!!

So it's for the Renaults, then. How much of it is Nissan's contribution? This reminds me of when Daimler frenched-up the mk2 version of an otherwise dumbed-down Plymouth Neon. From that and the Dodge, how the hell did Fiat's Dart get the Neon's glovebox?

While not hand made, why can't this engine be used as the base versions of the C and E Class and the various other derivatives of those platforms? Couldn't that tech be good for at least 325-350 up in those ther models? That why the hand built ones still get to be the power leaders and be special, but other vehicles get to have both a power, yet fuel efficient base more. Let me take that back, for while AMG's through the years have been power, fuel efficient many have not.

I get the feeling the resale value of the cars with this engine will be s hit.
Who would want to buy a used 2.0 liter engine boosted to the edge of it's life to make 416 hp after it was owned and used and abused by the first owner for 30k-40k miles?
